As a project sponsor and investor, CA Immo International is confronted with numerous sensitive issues arising from the needs of environmental and nature protection and urban development, as well as cityscape and ensemble conservation. Its activities are guided by an acute awareness of ecological operating principles, whose implementation also involves external facility managers. As regards premises management, the principal focus is on technological measures to ensure that energy resources are managed efficiently. These include the thermal optimisation of building carcasses, renovating heating systems and improving energy use in office buildings. The main issue in new and remodelled buildings is workplace quality. CA Immo International also complies with modern ecological building methods, including the use of low-emission and long-life materials.
